Abstract
Recently, adaptations of the sliding filament model (1) have been proposed as a description of the dynamic properties of the contractile mechanism which provide an explanation of the transient force response after a quick change in length in which data of the ultrastructure and the biochemical reactions are taken into account (2,3,4). The present experiments were undertaken as a contribution to the identification of the reaction steps of the kinetic scheme (5) in the transient force response. In a preceding study attention was focused on the early parts of the tension response of frog sartorius muscle (6). From these experiments it was concluded that the initial fall in tension during a fast shortening can be described in terms of a visco-elastic element. Furthermore, it was found that in the metabolically inhibited muscle in which the ATP concentration was lowered by repeated stimulation, the early phases of the tension recovery are depressed.
